Encyclopedia Entry:
This species forms the majority of fairy monsters living in forests. They sport a child-like appearance and behavior, and have a youthful-aura around them. They also love to sing and dance, and are generally harmless toward humans. In fact, humans don’t usually refer to them as monsters. However, beware if they are under the influence of a succubus’ magic, and treat them the same way you would treat a succubus-type monster.
When fairies become a monster under said influence, the will attack human males in numbers to squeeze out their spirit energy through their semen. Fairies are weak by themselves, so it is same to capture one and even rear it yourself instead of chasing it away, should you be attacked by a lone fairy. However, you will be in deep trouble with a group of them, who will envelope you and treat you as their plaything until you run out of breath.
